Revision 708c28e2
Added by J. Moringen almost 7 years ago

Added remote introspection in src/introspection/remote-introspection.lisp

fixes #1744, fixes #1830, fixes #1833

The remote introspection implementation consists of three layers:
  • `introspection-receiver' handles the event protocol and dispatches
    broadcasts and replies
  • database object classes `{participant,process,host}-entry' are stored
    and maintained in a `remote-introspection-database'
  • `remote-introspection' is a participant class that ties everything
    together by instantiating and configuring `introspection-receiver'
    instances and a database and performing timed updates.
  • src/introspection/protocol.lisp (database-change-hook): new generic
    function; return the change hook of an introspection database object
    (introspection-survey): new generic function; survey remote objects
    (introspection-ping): new generic function; ping a remote object
    (entry-info): new generic function; return info instance associated to
    entry object
    (entry-parent): new generic function; return parent entry of an entry
    (entry-children): new generic function; return child entries of an
    entry
  • src/introspection/mixins.lisp (change-hook-mixin): new class; can be
    mixed into database classes to provide a change hook
    (database-change-hook): new method; return database change hook
  • src/introspection/remote-introspection.lisp: new file; contains remote
    introspection implementation with `introspection-receiver',
    `{participant,process,host}-entry', `remote-introspection-database'
    and `remote-introspection' classes
  • src/introspection/package.lisp (package rsb.introspection): added
    imported-from rsb.patterns.request-reply symbols remote-call-error,
    future-done? future-result, server-method and call; added exported
    symbols database-change-hook, introspection-survey,
    introspection-ping, entry-info, participant-entry, entry-parent,
    entry-children, process-entry and host-entry
  • test/introspection/remote-introspection.lisp: new file; unit tests for
    remote introspection functionality
  • test/introspection/package.lisp (package rsb.introspection.test):
    added imported-from rsb.introspection symbol
    remote-introspection-database
  • rsb-introspection.asd (system rsb-introspection): added file
    src/introspection/remote-introspection.lisp
    (system rsb-introspection-test): added file
    test/introspection/remote-introspection.lisp
